I completely agree with blondie9999 on this.  Having made some clothing for Gen4 figures in the past I have recently  tried making some clothing for Genesis figures, and converting things from Gen4. Not just to the base Genesis figure, but to fit some of the shapes. It is a LOT easier to make things for Genesis.

One of the things that make it easier is the DS4 collision detection which works on clothing, and will automatically fix pokethrough.
